leit'known that Llloounn l'. CooonsrniLL, a citizen of the UnitedStates, and aresident of lvortendylre, in the county of lergcn and Stateof NeWJersey, have invented a new and Improved Steam-J et Flueleaner, ofwhich tho following is a full, clear, and exact description.

This invention relates to a class of boiler 'tube or ilue cleaners whichproject a forcible The invention consists in the novel tea-A tu res ofconstruction and combination of parts, is hereinafter described, anddefined iu the appended claims.

Reference is to be had to the accompanying drawings, forming; npart ofthis peciication, in which similar characters of reference indi,- catecorresponding parts in all the figures.

Figure 'l is aside view of theiinproved fluccleaner applied to aportieri of a iine indicated by dotted lines. 2 is a longitudinalsectional View taken substantiallyen the line 2 E in Fig. i, and Fig. 2lis an end View oi the device seen in the direction ot the ai row in Fig.

rilie improvement :is represented coin prises a conical shell or bodyAl,'wliich is partly closed at the larger end by :in annular Wall 5,troni which centrally projects a collar G, internally threaded forscrewed engagement therewith of one end of the blowenpipe 7. From thesmaller end ot the conitorni body e extends a nozzle 8 i-n cylindricalforni, tlie bore f) of which is ot a proper diameter to adapt saidnozzle for eilective service. Preferably the nozzle S is so reduced inthe diaineter et its bore that the diameter of the blowerpipe exceedsit, which gives great force to the steem-jetissuing from .the nozzle andadapt-s .the flue-cleaner for highlyefcient service,

While using but a small amount of steam.

' Another feature of invention, as shown,

comprises a series ot similar winne 1a. ero

jected from the outersurfaceoi the coniiorin. bod57 et, theseequallv-spificed Wings twisting j spirally in the same direction, sothat they are disposed substantially parallel with each other,andrepresent portions of coarsepitchcd screw-threads, as clearly indicatediiigs. l and Theblowenpipe (shown partially) incornplete 'form isadapted for 'lexilole connection with a source of yh.igl1piessuresteainsupply, as is eorninon for such devices, and oi' course means to controlthe linilnx ot steam into the blower-pipe is provided therefor.

ln operation the hollow` headflrtltl-ll,

end

of the pipe 7 `is introdnced within the e d of" one of a pluralitfyfeMfines or tubes A in a boiler that need cleaning. Steam of high pressureis passed. throiigh the blower-pipe? into the conitorin head 4 indhighly heats said heed,'the 'Well of which is. comparatively thin toadapt it to become heated quickly,

which is very essential for the proper operation of the improvedfluo-clennen It will be seen in Fig. l thet the Wings lll prevent thecomplete entrance of the hollow head e within thetine A., and thecontzictol said wings `with the tube or iiue will serve to center thehead 4 and nozzle S therein. The pressure oi steam that passes into andthrough the blower-heed and nozzle thereon will cause a e-.irreilt oil'air to be drawn between the wings l0 over the coniforni head or body etand mingled with the steam-jet, this induction ot atmospheric air beingeffected bythe partiel vacuum produced in the lue by the rapid currentof steein entering the saine. As the forcible air-current iningles withthe stean'i-jet so as to cause 'the air and steam currents to twist inthe saine direction, these combined jets coact'withiorco upon the looseseele and soot that clog tho flue., blowing such obstructions out of theoppo `te end ot' the liuc.

Having thus described in v invention, l elztiin ns new and desire tosecure by Letters PatentN l. The combination with the coniformblower-head, and a plurality of spirelly-disposed and equallyspaeedWingsthereon, of f a blowenpipe'at the larger end o the poniTl `forniblowenhead, and a cyiindlictl nozzle-fk projected frointhe smitlilcrendof saidiblowerun 'y beati-having less internal diameter than theblower-pipe for the purpose set forth.

2.. The combination with a 'bloWer-pipe,and

a hollow coniformbloWer-heed seenreflrle4 thereonatthe larger end ofsaid blower-head,

the side wall of the latter being thin to adept it to heat quickly whensteam passes there-' u through, of a plurality of epirally-disposedwings on the exterior of the blower-head equally spaced apart andtrending in the same direction, and a j et-nozzle 'extending from thesmaller end of the blower-head, having less internal diameter' than thatof the blower- HOOKER I.` COGG'ESIIALL.
